ABSTRACT:
A pressure sensitive multiple resistor element is proposed whereby two or more variations of resistance can be obtained simultaneously by applying a single compressive force. It comprises an anisotropically electroconductive composite sheet exhibiting varied resistance between its opposite surface as a result of the compressive force applied thereto, a set of electrodes provided on one surface of the composite sheet, another set of electrodes provided on the other surface, and a means for applying the compressive force to the composite sheet through the electrodes. The anisotropically electroconductive composite sheet is formed of an electrically insulating rubbery elastomer as the matrix within which many electroconductive fibers are dispersed and oriented in the direction perpendicular to the plane of the sheet.
